The 5-foot-10, 178-pound Parks spent most of last season on the St. Louis Rams’ practice squad before being signed to the 53-man roster Dec. 26. He was among six players released Tuesday.

Earlier this spring, the club claimed wide receiver and former University of Washington quarterback Isaiah Stanback (Patriots), wide receiver Kole Heckendorf (Lions) and quarterback Mike Reilly (Rams) off waivers. Reilly has since been released.

Parks, whose first name is Cordelius, was a two-year starter at Northeastern and signed with the Rams after the draft in 2009.

Parks joins a crowded Seahawks’ secondary as the 10th cornerback on the roster. But fourth-round draft choice Walter Thurmond and fellow rookie Josh Pinkard have been sidelined this spring – Thurmond while rehabbing the torn knee ligaments that ended his senior season at Oregon and Pinkard also with a knee injury.

The other corners are Marcus Trufant and Josh Wilson, the incumbent starters; former first-round draft choice Kelly Jennings, who has drawn praise from coach Pete Carroll and defensive coordinator Gus Bradley for his performance this spring; ex-Washing ton Husky Roy Lewis, who has been working with Jennings in the No. 2 defense; Kennard Cox and Marcus Brown, the corners in the No. 3 defense; and rookie Chris Richards.
